Nā Attenuators Hoʻololi Waveguide

I nā kaapuni microwave, kiʻekiʻe pinepine ka mana o nā hōʻailona. Inā ʻaʻole hiki ke hoʻomalu piha ʻia ka mana nui, e maʻalahi ia i nā pilikia he nui i ke kaapuni, e like me ka ʻoi aku o ka nui o ka ikehu hoʻomanawanui o nā ʻāpana kaapuni a me ka hoʻololi ʻana i nā ʻano like ʻole. Hiki i ka hoʻohana ʻana i nā attenuators variable waveguide ke hoʻokō pono i ka koi no ka hōʻemi ʻana i ka mana hōʻailona a hōʻoia i ka hana maʻamau o nā kaʻa microwave.
Hoʻokumu ʻia ke kumu hana o ka attenuator hoʻololi mau i nā hiʻohiʻona hoʻolaha o nā hawewe electromagnetic i nā alakaʻi nalu. Aia ka nui o nā alakaʻi nalu, nā mea hoʻohālikelike impedance, a me nā poloka conductor variable. Ke hele ka hōʻailona ma kahi alakaʻi nalu, hoʻopili ʻia kahi ʻāpana o ka ikehu e ka poloka conductor, a laila e hōʻemi ana i ka mana hōʻailona.
Inā he ʻano mechanical ka pahu conductor i hiki ke hoʻoponopono lima ʻia e ka mea hoʻohana, he rotary stepped attenuators. ʻO nā attenuators hoʻololi lima he mau mea kōkua nui i nā ʻōnaehana kamaʻilio uila.

Noi:

1. No ka hōʻoia ʻana i ke kaulike o nā pae hōʻailona ma ke kaulahao hōʻailona, hiki ke hoʻokō ʻia nā attenuators variable waveguide ma ka hōʻemi ʻana i ka ikaika hōʻailona.
2. ʻO ka hoʻonui ʻana i ka laulā ikaika o ka ʻōnaehana he wahi ikaika ia o ka rotary stepped attenuator, hiki ke hōʻoia i ka hana paʻa o ka ʻōnaehana.
3. ʻO ka hāʻawi ʻana i ka hoʻohālikelike impedance hiki ke pale i ka noʻonoʻo ʻana i ka hōʻailona a me ka nalowale, e hōʻoia ana i ka paʻa o ka hoʻouna ʻana i ka hōʻailona.

Hoʻohana nui ʻia ka waveguide variable attenuator i ke kamaʻilio microwave a me ka hoʻāʻo ʻana o ke keʻena. Hiki ke hoʻohana ʻia e hoʻoponopono i ka ikaika hōʻailona e hoʻokō i nā pono like ʻole. No ka laʻana, i loko o ka hale hana, hiki i ka rotary step ke hāʻawi i nā hiki ke hoʻololi i ka wā e pono ai ke hoʻololi i ka ikaika hōʻailona e hoʻāʻo ai i ka hana o nā mea hana. I ke kamaʻilio microwave, hiki ke hoʻohana ʻia nā attenuators hoʻololi mau e hoʻoponopono i ka ikaika hōʻailona e hōʻoia ai ʻaʻole ikaika a nāwaliwali paha ka hōʻailona i ka wā o ka lawe ʻana.
ʻO nā mea maikaʻi o nā attenuators variable he maʻalahi, maʻalahi o ka hoʻohana ʻana, a me ka hoʻoponopono maʻalahi. Ma ka hana lima, hiki i nā mea hoʻohana ke hoʻomalu pono i ka nui o ka hōʻailona hōʻailona e like me ka mea e pono ai. Eia nō naʻe, ke hoʻohālikelike ʻia me nā attenuators alakaʻi nalu, ʻoi aku ka liʻiliʻi o ka laulā hoʻoponopono o nā attenuators manual waveguide, a pono ke kaʻina hana hoʻoponopono i kahi manawa a me ka pololei.

Kaʻaleʻaleʻahāʻawi i ka VSWR haʻahaʻa a me ka palahalaha attenuation kiʻekiʻe mai 0.96 a i 500GHz. ʻO ka laulā attenuation he 0 ~ 40dB.
